If the trainer changes environment or tone but the dog still performs the same response to the cue, this demonstrates:

• A. Habituation
• B. Generalization
• C. Stimulus control with some generalization
• D. Extinction

Answer: (C)

This shows how a cue can come to control a dog's behavior across different contexts. When the dog still performs the same response to the cue even if the environment or the trainer’s tone changes, the cue has gained control over the behavior beyond the exact training situation. That demonstrates stimulus control, and because the response occurs despite some variation in context, there is generalization present—but not perfect or universal, hence “stimulus control with some generalization.” Habituation would involve a diminished reaction to a repeated neutral stimulus, and extinction would be the loss of the response when reinforcement stops, neither of which is occurring here.
